III. INSTALLATION
2. System Memory (DRAM)
This baseboard supports eight 72-pin SIMMs (Single Inline Memory Modules) of
4MB, 8MB, 16MB, 32MB, 64MB, 128MB to form a memory size between 8MB to
1GB. The DRAM can be either 60ns or 70ns Fast Page Mode (Asymmetric or
Symmetric), Extended Data Output (EDO), or Burst Extended Data Output (BEDO)
(with C-P6ND only). SIMMs must be installed in pairs so that each bank contains
two of the same size memory modules. To support ECC, you must use true (op-
posed to phantom parity generated by TTL chips) 36-bit parity-type SIMM (e.g. 8
chips + 4 parity chips) in pairs for all modules. Mixing 32-bit non-parity SIMM
(e.g. 8 chips) and 36-bit SIMM (e.g. 12 chips) will work minus the ECC feature.
IMPORTANT: Memory setup is required in “Auto Configuration” in the
CHIPSET FEATURES SETUP of the BIOS software. Each bank must have
the same size memory installed in pairs.
Install memory in any or all of the banks in any combination as follows:
Bank Memory Module Total Memory
Bank 0 4, 8, 16, 32, 64, 128MB x2
SIMM Slots 1&2 72-pin FPM, EDO, BEDO SIMM
Bank 1 4, 8, 16, 32, 64, 128MB x2
SIMM Slots 3&4 72-pin FPM, EDO, BEDO SIMM
Bank 2 4, 8, 16, 32, 64, 128MB x2
SIMM Slots 5&6 72-pin FPM, EDO, BEDO SIMM
Bank 3 4, 8, 16, 32, 64, 128MB x2
SIMM Slots 7&8 72-pin FPM, EDO, BEDO SIMM
Total System Memory (Max 1GB) =
NOTE: Memory on socket 1 has a clearance of 5.0 cm when the C-PKND and
C-P6ND CPU cards are installed and 5.5 cm when the C-P55T2D CPU card is installed.
IMPORTANT : Each bank must have the same size memory installed in pairs. Do not
use memory modules with more than 24 chips per module. Modules with more than 24
chips exceed the design specifications of the memory subsystem and will be unstable.
i960 Local DRAM: The i960 requires 4MB to 256MB (16MB recommended)
memory using one or two EDO DRAM modules when 960SEL jumper is set to
“I2O.” The i960 does not require memory in the “Bridge” mode. Use i960 SIMM
socket 1 when using only one module. The i960 does not support parity or ECC.
